You sound like an absolutely incredible grandparent to me.
Do your children appreciate the enormous sacrifice you are making?
I know for sure that I would not be prepared to do that.
A lovely friend of mines mother was just like you. She was full time childcare to her eldest sons 4 children. Yes, they had 4 children because they didn't have childcare costs (they were honest about that).
My friend stuck to 2 children because that's what she could afford comfortably with childcare costs etc. She never so much as asked her mother to babysit, she could see that her mother was wrecked from her days childminding.
Her mother was 14 years unpaid full-time childcare. She loved the children but she felt so completely restricted in her life.
She had a massive stroke in her mid 60's and languished for a couple of years in a home until she died.
Her son rarely visited, leaving it to my friend to that.
There is absolutely no way that I would be giving my life up to do similar.
Emergency help yes, a bit of babysitting yes.
Being full-time childcare. Fxxx No.
Too much to ask.
I don't believe for one second, in my experience, that most adult children appreciate that type of sacrifice, that a grandparent is making, at that stage of their life, to be providing full-time childcare.
For you @shippingnews💐
